The verdict in three sentences
If you already write HTML and CSS, JavaScript is the skill that turns a static page into a useful tool: calculator, validated form, catalogue with cart, WhatsApp ordering. In Saint-Louis, learning online saves you a move to Dakar and a bootcamp at 500,000 FCFA or more. The Kolonell course costs 75,000 FCFA for 16 hours and two concrete projects to show.
Why JavaScript after HTML and CSS
In Saint-Louis, between UGB students, computer science graduates and self-taught learners studying on their phones, many can build a showcase site. What is most often missing is the part that makes the page react: showing a price based on quantity, checking a phone number before sending, loading products from a file or an API, keeping a cart in memory. That is exactly what a client or recruiter asks about in the first interview.
| What you can do | With HTML and CSS only | With JavaScript as well |
|---|---|---|
| Presentation page | Yes | Yes, with animations and menus |
| Contact form | Fields displayed | Validation, error messages, clean submission |
| Price calculator | No | Yes, in real time |
| Product catalogue | Fixed list | Filters, search, cart |
| WhatsApp ordering | Simple link | Pre-filled message with the cart |
| External data | No | API calls with fetch |
| Freelance rate for a site (order of magnitude) | 100,000 to 200,000 FCFA | 200,000 to 500,000 FCFA |
Options for learning from Saint-Louis
| Option | 2026 cost (FCFA) | Duration | Strengths | Limits |
|---|---|---|---|---|
| Free tutorials (YouTube, freeCodeCamp) | 0 | Variable | Free, extensive | No clear path, frequent dropout |
| Bootcamp in Dakar | 500,000 to 1,500,000 | 3 to 6 months | Intensive coaching | Cost, Dakar rent, full time |
| University course | Included in fees | One semester | Theoretical base | Few projects from the local market |
| Kolonell JavaScript course | 75,000 | 16 h, at your own pace | 2 projects, tested exercises, certificate | Requires consistency |
The course JavaScript: make a website come alive and interactive is level 3 (intermediate) of the web development track, at 75,000 FCFA (115 EUR) for 16 hours, taught in French. Six modules: language basics, functions, arrays and objects, the DOM and events, forms, validation and local storage, asynchronous code with fetch and APIs, then organising, debugging and publishing. The main project is an interactive catalogue with cart and WhatsApp ordering. It belongs to the Web development track, which leads up to full-stack: all 5 levels together cost 350,000 FCFA instead of 450,000.
Jobs and income: 2026 orders of magnitude
The figures below are estimates for Senegal, to be read as benchmarks, not guarantees. A portfolio with two or three live projects weighs more than a degree alone in an interview.
| Opportunity | 2026 pay (FCFA) | Realistic delay after the course |
|---|---|---|
| Developer internship (Dakar or remote) | 50,000 to 100,000 per month | 1 to 3 months of applications |
| Junior developer job | 250,000 to 450,000 per month | 6 to 12 months, with React next |
| First freelance job (interactive site) | 100,000 to 300,000 per project | 1 to 3 months |
| Adding a calculator or form to an existing site | 50,000 to 150,000 | From the first weeks |
| Work for the diaspora or abroad | Variable, often in EUR | With a solid portfolio |
Mini case study
Moussa, 22, a computer science undergraduate at UGB, has built a few HTML and CSS sites for friends. He takes the 75,000 FCFA JavaScript course over three weeks, one hour each evening. He publishes the catalogue with WhatsApp cart, then adapts it for a cosmetics shop in Sor that pays him 150,000 FCFA.
Learn this skill with Kolonell Academy
Short, practical online courses (taught in French), graded exercises, certificate. Pay with Wave or Orange Money.
Simple calculation: this first job pays back the course twice. If he then lands an internship at 75,000 FCFA a month, the investment is covered in the first month. Nothing is automatic: he had to approach about ten shops before getting a yes.
FAQ
Do I need HTML and CSS first?
Yes, it is an intermediate level. If you are starting from zero, begin with level 2 of the track, HTML and CSS, 12 hours.
Is a computer required?
Yes, you need a computer, even an entry-level one, with a browser and a free editor such as VS Code. A shared 4G connection is enough to follow the 16 hours.
Is JavaScript enough to get a job?
For an internship or freelance work, often yes. For a junior developer job at 250,000 FCFA and above, recruiters usually expect a framework such as React, taught at the next level.
